Conrad (Connecting or Corner Radius)
Conrad is another really nice feature of the ProtoTRAK EMX. In the example below
you could machine a straight line from Point A to B, then an ARC with radius R from
B to D, then another straight line from D to E.
The problem is that the arc is not easy to program because you often don’t know
where point D or B, or the center of R is located. However, you may know where
Point C is, or you may be able to figure it out easily. In that case you can program
the above part by programming a straight line from A to C, tell the control when it
asks that you have a CONRAD equal to R, and then program another straight line
from C to E. The ProtoTRAK will automatically blend the connecting radius (CONRAD
R) between the two straight lines with no additional input.
For Rectangular Pockets or Profiles, CONRAD stands for corner radius. You may
input any value that makes sense considering the size of the pocket and the
diameter of the tool.
